EPA range on the RAV4 EV is officially 103 miles. It has a 41.8 kwh battery, bigger than Model S' 40 kwh. It supposedly uses the same drive train as the Model S. It certainly is not as aerodynamic. But it might weigh less. This has me a bit confused about expected Model S 40 khw range. Given the Model S 85 kwh battery's 300 mile range at 55 mph and 265 miles EPA range, the same ratio for the 40 kwh battery's publicized 160 miles at 55 mph results in a 141 mile EPA range estimate. Do people think any valid comparisons can be drawn or estimations made for Model S 40 kwh ranges based on the RAV4 EV? Could Models S 40 kwh range fall short of expectations even at a steady 55 mph? Why is the RAV4 EV EPA range so low with the same drive train and bigger battery? I'd appreciate any well considered thoughts on the matter.
